    Quantitative analysis of how Myc controls T cell proteomes and metabolic pathways during T cell activation

    Julia M Marchingo et al.
    Myc-dependent induction of amino acid transporter expression in response to T cell receptor activation is essential to enable T cell proteome remodelling upon immune activation.

    MYC and Twist1 cooperate to drive metastasis by eliciting crosstalk between cancer and innate immunity

    Renumathy Dhanasekaran et al.
    MYC and Twist1 drive metastasis by a novel non-cell-autonomous transcriptional mechanism of eliciting a cytokinome that mediates the crosstalk between cancer cells and macrophages, and its therapeutic blockade inhibits metastasis.

    TAPBPR alters MHC class I peptide presentation by functioning as a peptide exchange catalyst

    Clemens Hermann et al.
    We reveal TAPBPR is a peptide exchange catalyst which restricts the peptide repertoire presented by MHC I on cells, a finding which has important implications for all aspects of immune recognition.

    TAPBPR bridges UDP-glucose:glycoprotein glucosyltransferase 1 onto MHC class I to provide quality control in the antigen presentation pathway

    Andreas Neerincx et al.
    The recently discovered peptide editor TAPBPR binds to UDP-glucose:glycoprotein glucosyltransferase 1 to provide quality control in the antigen presentation pathway by facilitating the reglucosylation of the glycan on MHC class I molecules.

    Expression levels of MHC class I molecules are inversely correlated with promiscuity of peptide binding

    Paul E Chappell et al.
    The number of different peptides presented by major histocompatibility complex class I molecules to the immune system's T lymphocytes is inversely correlated with cell surface expression and is strongly associated with the response to infectious disease.

    Mice deficient of Myc super-enhancer region reveal differential control mechanism between normal and pathological growth

    Kashyap Dave et al.
    A tumor-specific regulatory region has been identified upstream of the Myc oncogene.

    Lymph node stromal cells constrain immunity via MHC class II self-antigen presentation

    Antonio P Baptista et al.
    MHC class II-mediated self-antigen presentation by lymph node stromal cells controls regulatory T cell homeostasis, thus safeguarding immune tolerance.

    TAPBPR mediates peptide dissociation from MHC class I using a leucine lever

    F Tudor Ilca et al.
    Immunopeptidomics in combination with novel cell-based assays that assess peptide exchange reveal a critical role for the K22-D35 loop of TAPBPR in mediating peptide dissociation and peptide selection on MHC I.

    A loop structure allows TAPBPR to exert its dual function as MHC I chaperone and peptide editor

    Lina Sagert et al.
    A dedicated structural element facilitates chaperone and antigenic peptide selector function of TAP-associated glycoprotein, a major quality assurance auditor in adaptive immunity.

    eIF4E S209 phosphorylation licenses myc- and stress-driven oncogenesis

    Hang Ruan et al.
    Genetic and transcriptomic analyses revealed that eIF4E S209 phosphorylation enables Myc and mutant KRAS cooperation in colon cancer through stress- and glutamine-dependent growth and addiction.
